Title: Flavor Dependence of T-odd PDFs

Abstract

The flavor dependence of the naive time reversal odd ("T-odd'') parton distributions for $u$- and $d$-quarks are explored in the spectator model. The flavor dependence of $$h_{1}^{\perp}$$ is of significance for the analysis of the azimuthal $$\cos(2\phi)$$ asymmetries in unpolarized SIDIS and DY-processes, as well as for the overall physical understanding of the distribution of transversely polarized quarks in unpolarized nucleons. As a by-product of the formalism, we calculate the chiral-odd but ``T-even'' function $$h_{1L}^{\perp}$$ which enables us to present a prediction for the single spin asymmetry $$A_{UL}^{\sin(2\phi)}$$ for a longitudinally polarized target in SIDIS.
